In-plane resistance of an ultra thin gold film: Influence of a copper phthalocyanine overlayer

We have constructed an apparatus to evaporate ultra thin films of Copper Phthalocyanine (CuPc) on ultra thin gold epitaxial film grown by MBE, which thicknesses are in the range of 30Angstrom. We present STM pictures of CuPc on ultra thin gold which show a columnar alignment perpendicular to the substrate and preliminary in-situ resistance measurement of the hybrid device. Using theoretical modeling on a simpler system, we calculate the electronic properties and estimate the expected changes in the quantum and temperature dependent resistance of the thin gold layer, when it is covered by a discotic overlayer.
